Title: Device for application of microwaves to generate plasmas in vacuum environment with and without use of electron resonance
Inventor: DATHE BERND
IPC: H01J37/32
Filed: 1998-07-03
Abstract: A device has a magnetron (1) coupled directly to a coaxial conductor length (3). Matching to a load impedance is via a signal extraction and suitable tuning elements.

Title: Guide roller for application on conveyor belts
Inventor: GAMBERINI ROBERTO
IPC: B65G39/02
Filed: 1999-01-18
Abstract: The guide rollers (5) have a freely rotating cylindrical sleeve (6) with a central support shaft (70), projecting from the sleeve ends and associated with belt (4) side supporting walls (8). A pair of flanges (9) can rotate along and around the sleeve independently of each other. A flexible yield (10) operates on each of the flanges to face the flanges to each other in reciprocal contact in a neutral non-operating end position in which the flanges cover the sleeve outer surface. The flanges each consist of a discoid end section (11) in contact with the belt and of a cylindrical section (12) for coupling with the outer surface of the sleeve which partially houses the corresponding flexible yield. The flexible yield consist of a spring (13) for each of the flanges, fitted coaxially on the respective sleeve and secured at its end within a seat made in the internal flange circumference and respectively inside a corresponding cup (15) associated with the sleeve end. The flanges can move away from each other axially along a direction parallel to the longitudinal axis of the other roller and in opposite directions at the point of contact with the belt and can rotate independently to enable the flange-sleeve assembly gradually to rotate according to the surface area of the belt in contact with the guide roller.
